【摘要】：伺服系統(tǒng)測試平臺是在進行伺服系統(tǒng)各項地面測試試驗的過程中使用的非標地面測試設備。由于其是保障各個類軍工產品的研制進度,批產速度以及裝備進度的重要設備,其對國防建設,保障國家安全都有重要意義。由于測試平臺是通過各個對外接口實現(xiàn)與伺服系統(tǒng)間的數(shù)據(jù)傳輸以及采集伺服系統(tǒng)外部傳感器數(shù)據(jù)的功能。因此,一般的測試設備都需要根據(jù)不同類型的伺服系統(tǒng)進行定制設計,不僅生產設計周期長,而且在出現(xiàn)技術問題時更改維護麻煩。導致由于測試設備影響伺服系統(tǒng)交付進度,進而影響整個項目研制進度的情況屢屢發(fā)生。本論文的研究目的是以搭載1553B總線、CAN總線和模擬輸入輸出板卡的PCI平臺工控機為核心,設計一套價格便宜且功能強大的伺服系統(tǒng)綜合仿真測試平臺。設計完成后的測試平臺不僅能夠滿足多個型號伺服系統(tǒng)測試試驗的使用,還由于在設計時引入通用化設計理念,減少了未來測試設備的研制周期。本文首先介紹了伺服系統(tǒng)測試平臺的分類和工作原理。之后,分析了任務書需求,設計了包括線性電源,電壓電流傳感器,模擬信號隔離模塊以及全屏蔽的測試轉接箱和電纜網(wǎng)組成的配套硬件系統(tǒng)。同時,為了滿足數(shù)字總線精確定時,數(shù)模同步觸發(fā)以及高速模擬信號采集處理的測試精度要求,開發(fā)了包含1553B雙緩沖消息隊列,虛擬硬件時鐘定時,同步觸發(fā)以及高速模擬數(shù)據(jù)處理功能的測試平臺軟件。最后,介紹了對測試平臺進行各項檢定測試、仿真測試及實驗驗證的方法和驗證測試結果。驗證測試結果表明,測試平臺的設計與生產都符合預期的設計技術指標。其不僅具有高效精確的采集測試功能,而且操作簡潔方便,提高了伺服系統(tǒng)的生產速度。
[Abstract]:The servo system test platform is a non-standard ground test equipment used in the ground test of servo system. Because it is an important equipment to guarantee the development progress, batch production speed and equipment progress of various kinds of military products, it is of great significance to national defense construction and national security. Because the test platform realizes the data transmission between the servo system and the servo system through each external interface and the function of collecting the external sensor data of the servo system. Therefore, the general test equipment needs to be customized according to different types of servo system. It not only has a long production design period, but also changes the maintenance trouble when technical problems occur. As a result of the test equipment affecting the servo system delivery progress, and then affect the development of the whole project often occurs. The purpose of this paper is to design a cheap and powerful integrated simulation and testing platform of servo system based on PCI platform industrial control computer with 1553B bus, CAN bus and analog input and output board. After the design, the test platform can not only meet the test of multiple models of servo system, but also reduce the development period of the future test equipment because of the introduction of the general design concept in the design. This paper first introduces the classification and working principle of servo system test platform. After that, the requirements of the taskbook are analyzed, and a complete hardware system consisting of linear power supply, voltage and current sensor, analog signal isolation module, fully shielded test transfer box and cable network is designed. At the same time, in order to meet the precision requirements of digital bus precise timing, digital-analog synchronous trigger and high-speed analog signal acquisition and processing, a 1553B double buffer message queue and a virtual hardware clock timing are developed. Test platform software for synchronous trigger and high-speed analog data processing. Finally, the methods and results of verification, simulation and verification of the test platform are introduced. The test results show that the design and production of the test platform are in line with the expected design specifications. It not only has high efficiency and accurate collection and testing function, but also has simple and convenient operation, and improves the production speed of servo system.
